Animal deliberately enclosed (5)
I believe the answer is:
ratel
'animal' is the definition.
(I know that ratel is a type of animal)
'deliberately enclosed' is the wordplay.
'enclosed' indicates a hidden word (the answer is enclosed within the clue).
'RATEL' is hidden within 'deliberately'.
(Other definitions for ratel that I've seen before include "wild animal" , "Badger-like animal" , "Honey-badger" , "creature with sweet tooth" , "Badger-like creature" .)
